We analytically study different fragments of existence and of it’s causes. Also synthetically we tend to integrate and interlink different domains. So here is a question from Mundak Upnishad, that hints about cosmic integral point.

We can understand this, by the formula- Distance = Speed × Time. When we observe a coin even from 90° above the bottom, time {for observation of light (coming from coin)} is constant for both phase of light. i.e. (1) In the air (2) In the other refractive media (like water).

We can understand this, by the formula- Distance = Speed × Time.
When we observe a coin even from 90° above the bottom, time {for observation of light (coming from coin)} is constant for both phase of light. i.e. (1) In the air (2) In the other refractive media (like water). It means, in the same duration of time, we are looking at the distance traveled by light in both media (e.g. water and air).
As we know, the speed of light decreases in water. So, the distance that it travels in the same duration of time, in water, appears to be lesser, than that in the air. Thus, the coin appears to be at a lesser depth.
[Main concept behind the phenomena- Apparent relativity of speed, time and distance. For example- When we see a Jet airplane flying in air or a train running at a distance. Both appear to move slowly. Reason- Distance for observation can be within two palms placed at the side of both eyes.]
